Broccoli is a well-known health-care vegetable. It can be better to eat more often, and it also has a certain regulating effect on blood pressure. And the cultivation of broccoli is not complicated. As long as you pay attention to scientific management, you can easily produce high yields. Below, we will talk about the technical points of broccoli planting.
First, planting time
The most suitable temperature for broccoli plants is between 5° and 25°, so the general sowing time is in the spring and autumn, so that it can grow better. This kind of plant is not drought-tolerant or flood-tolerant, so be sure to pay more attention to management when watering.
Of course, nowadays, after the greenhouse, many vegetables are not needed to consider the season. In the greenhouse, broccoli can be grown well in winter. In this case, it can be listed at the Spring Festival. At that time, there were fewer fresh vegetables, which just fill the gap in the market. It can sell a lot of money and bring good benefits to the growers.
Second, soil preparation
Choosing the soil for planting broccoli should be relatively loose and then have a strong water retention capacity. Because its growth is relatively large for fertilizers, it must be applied when applying fertilizer.
Then select the variety, it is recommended to select the kind of disease resistance is better, and then more resistant to cold varieties, the most suitable temperature for seed germination is about 20 ° C.
Third, colonization
When the seedlings grow out of 5 true leaves, they can be transplanted. Pay attention to the distance between each plant, and it is better to keep it at 35cm. Then you can put a layer of film on the ground, which can control the water dispersion, and also increase the temperature of the land.
Waiting until the colonization has been completed for half a month, it is time to start the first topdressing. Then wait until the buds to carry out the second top dressing. If it is planted in a greenhouse, it is important to keep a good temperature during this time. It should not be too high or too low. If the temperature is higher than 24 ° C, then the quality of the flower ball is not very good, if it is lower than 8 ° C, then the growth will enter a very slow period.
Fourth, disease prevention
Be sure to pay attention to prevent the occurrence of diseases. If you plant broccoli, it is easy to appear cabbage caterpillars, as well as aphids. When you first appear, you should pay attention to the right amount of medicine, but you can't use the medicine half a month before harvesting. .
The above is the key points of planting technology of broccoli organized by Hui Nong. I hope to help everyone.
